This invention relates to building construction and particularly to a novel and improved wall construction therefor.

In walls made of the artificial fiber board 5, constructions now being largely used in the place of the old lath and plaster constructions,.considerable difficulty is experienced in themaintenance of an even and permanently finished surface, largely due to the repeated expansion and contraction of the fibrous sheet-s making up the Walls under the influence of changes in temperature and moisture conditions. It is the practice to separate the fibrous sheets a dist-ance of, say one-quarter of an inch, or more, and to fill in the spaces with a plastic composition, and while this permits the free and independent expansion and contraction of the uxtaposed wall sheets, the diliiculty still remains of maintaining an 2o even and permanently finished surface at the joints between the juxtaposed sheets due to the yielding and ultimate loosening of the filling-in composition in response to the repeated expansions and contractions. By my invention a permanently even and finished surface is maintained notwithstanding these difficulties. According thereto, the fibrous sheets or boards are not only secured to the framework in the usual manner, sepa-rated and entirely out of contact with each other,

but are also directly joined together by elongated wire clasps bridging the gaps between them and permanently and firmly joined thereto which permits the free and unhindered contraction and expansion of the juxtaposed sheets and at the same time retains the filling-inr composition intact, enabling the retention of a permanently even and finished surface.

In the preferred embodiment the clasps are in the form of elongated strips of wire mesh with the cross-Wires of the mesh, having their free ends bent down at right angles to the plane of the mesh body, preferably pointed and forming integral attaching means whereby the clasp strips may be positioned over the filling-in composition between the adjacent fibrous boards or' sheets and readily secured tothe latter by imbedding the free ends of the cross mesh wires into the fibrous sheets with 192s. serial No. 291,673.

the clasp units disposed in the plane of the wall. rIhe flexibility of the wire mesh and the resiliency of the free ends of the cross wires permit them to yield in response to the expansions and contractions of the fibrous sheets, but the wire mesh units remain firmly and permanently secured to the wall sheets to maintain the filling-in compound intact within the spacings. 'Ihe wall may be finished in any suitable manner, as for example by coaty ing the same with coats of paint or layers of plaster or similar finishing materials.

y'Ihe invention is applicable to any of the standard constructions.

For a better understanding of the invention, reference may be had to the accompanying drawings forming a part of this application, wherein Fig. 1 is a perspective view of a section of the Wall embodying the invention,

Fig. 2 is a section along the lines 2 2 thereof,

Fig. 3 is a perspective View indicating the step of applying the special attaching and holding strip, and

Fig. 4 is a view of a strip for a corner construction. Y

Referring to the drawings, I have indicated a frame construction including the vertlcal studs 1, 2 and 3, the stud 1 being on the side wall and the studs 2 and 3 being at the corner. I have indicated sheets 4 and 5 of artificial fibrous boards which are to be secured to the side frame member or stud 1. These sheets are not positioned in abutting engage-` ment with each other, but are separated a short distance, as for example one-quarter of an inch or more, to provide a spacing 6 therebetween.. The boards or sheets 4 and 5 thus 90 spaced are firmly nailed to the frame member or stud 1 by nails 7 as indicated. The filling compound for the space 6'is indicated at 8 and this, ofcourse, may be any standard plaster or plastic composition. The sheets 4 and 5 are then bound directly to each other by a wire mesh clasp unit 9 having the ends of the cross Wires which project beyond the sides formed into securing nails 10, the unit bridging the gap 6 and being firmly secured 100 to the adjacent sheets 4 and 5 in'coplanar rebridging unit 9.

Fig. 3 indicates the positioning and securing of the unit 9 in position. This is done with the greatest facility, the ends 10 of the cross wires of the mesh being preferably 'pointed to facilitate the securing operation.

After the securing and positioning of the unit 9 into bridging relation with the sheets 4 and 5 flat against the surface thereof and against the filling-in material 8, the surface maybe finished in any desired manner, as for example by painting', plastering or the like (see 14) The units '9 for the side walls may conveniently include three longitudinal wires 9'.

The corner sheets 5 and 11 are secured to the 'studs 2 and 3 similarly to the securing of sheets 4 and 5 to the lstud 1 and the corner sheets are also secured together by the flexible` or resilient wire mesh unit 12 which is similar to the unit 9, the unit 12, however, being formed so as to fit into the corner, that is, with the cross wires bent at right angles to each other at the center of the strip. A similar plastic composition or other suitable Y filler is` introduced into the gap between the corner plates A5 and 11 and the surface is finished as described above in connection with the side wall. In this embodiment there are four longitudinal wires 12.

With a wall of this construction the surface remains permanently even and free from cracks and crevices and is therefore capable of receiving a permanent finish, substantially unaected by changes in temperature and moisture conditions, the wire mesh securing and bridging units 9 and 12 remaining firmly fastened to the sheets, retaining the filling-in material 8 intact and maintaining a permanently even surface and nish, notwithstanding changes in temperature and moisture conditions Moreover, the wire mesh units may be readily formed of ordinary cheap chickenwire and may be incorporated into the structure of the wall in an economical manner.

The artificial fibrous boards o sheets 4, 5 and 11 may beof any standard commercial product, as for example such as ifCelotex .which is formed of cane fibers, an may. be readily obtainedpn the market. T e invention, however, is not limited to any particular artificial board or sheet but is applicable to any wall construction made up of fibrous boardsfin which similar problems and difficulties arise.

I claim:

1. A building wall construction and th like including a frame member, a pair of artiintacto boards to the frame member in spaced relation to each other, a lilling-in material incorporated'into the gap between the boards, and an elongated wire mesh unit bridging the gap and firmly secured to the adjacent fibrous boards or sheets in coplanar relation therewith, said unit being secured to the adjacent lartificial fibrous sheets by the free ends of the cross wires of the mesh which are bent at right angles to the plane thereof and formed into yielding securing nails.

2. A building wall construction and the like including a frame member, a pair of artilicial fibrous boards secured to the frame member in spaced relation to each other, a filling-in plastic material incorporated into the gap between the boards, a fiat metallic reinforcing and retaining strip bridging the gap and permanently nailed to the adjacent fibrous boards or sheets in coplanar relation therewith and against the filling-in plastic i material, and a finishing layer applied to the wall surface, said filling-in material being separate from the finishing layer.

3. A building wall construction and the like including a frame member, a pair of artificial fibrous boa-rds, means for securingl the boards to the frame member in spaced relation to each other, and an elongated wire mesh unit bridging the gap and firmly secured to the adjacent fibrous boards by the free ends of the cross wires of the mesh which, being bent at an angle to the plane thereof and formed into yielding securing nails, are embedded into the boards.

In testimony whereof, I have signed my cial fibrous boards, means for securing the l
